Application filed October 27, 1922. Serial No. 597,408.

To all whom it may concern.

Be it known that I, MrL'roN M. Annnn, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Pyrotechnical Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates, generally, to improvements in pyrotechnical devices; and the invention has reference, more particularly, to an improved detonating fire-work or fire-cracker.

The invention has for its principal object to provide a novel construction of detonatingfire-work or fire-cracker which is safe to handle, which will not fly apart when set oil so as to-endanger the eyes or person of the user, or entail the risk of igniting fires, and

which is constructed to produce, when set detonations, rendering the same of pleasing and interesting effect, and providing a firework or'fire-cracker which will operate for a comparativelylong time after it is ignited.

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.

With the various objects of this invention in view, the same consists, primarily, in the novel detonating fire-work or fire-cracker hereinafter set forth; and, the invention consists, furthermore, in thenovel arrangements and combinations of the several devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described in the following specification, and then finally embodied in the claims appended thereto.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the complete firework or firecracker, showing one embodiment of this invention; Figure 2 is a vertical cross section through the same; Figure 3 is a plan view of a combustiblecarrier sheet upon which a plurality ofpastilles or V lozenges of 'pyrotechn'ical composition are mounted, and which is adapted to be wadded 'or crumpled up and then inserted in the Similar characters of reference are em' ployed in all of the hereinabove described views, to'indicate corresponding parts.

Referring now to said drawings, the reference character 1 indicates an outer casing or box, the upper wall of which is provided with an opening 2. Said casing or box 1 is provided at its'opposite ends with end-flaps 8 provided with tuck-fiaps4, whereby the ends of the casing or box are normally closed. Provided in said end-flaps 3 or at other points in the sides of the complete casing are a plurality of ventilating perforations 5, which permit access of air into the interior chamber (Sprovided by the casing or box. The said casing or box is preferably made of comparatively heavy paper or light cardboard. I

The reference character 7 indicates a combustible carrier sheet preferably made of thinpaper, such as tissue paper, upon which are caused to adhere a plurality of pastilles or lozenges S-consis'ting of a pyrotechnical composition adapted to produce detonations when ignited. It will, of course, be understood that there are many different pyrotechnical compositionsknown to those skilled in the art which, when ignited, will produce detonations, and consequently, in this respect I do not desire to limit myself tothe use of any particular composition so characterized, although I prefer to 'employ a composition heretofore known and used to produce intermittent detonations, and which comprises a mixture of gum-arabic, carbonate of mogulsium, white phosphorus, red ocher and potassiumchlorate. The pastilles or lozenges 8 of pyrotechnical composition are arranged in a group, the members of which are suitably spaced apart- It'is preferable to treat the paper or other carrier sheet 7 with some chemical adapted to insure continued combustion thereof once the same is ignited; A chemical such as saltpeter mayself to the use of that suljistan'ce for the purpose indicated.

l ter the carrier sheet 7 with its group of spaced apart pastilles or lozenges of pyrotecluiical composition 8 in adhering relation thereto is prepared, and the casing 1 is set up to receive the same, the said carrier sheet 7 is crumpled up and inserted through the opening 2 so as to be enclosed within the interior of the casing 1. If desired one or more of the corners 7 of the carrier sheet 7 may be left protruding outwardly from the interior oi the casing 1 through the opening 2, so as to provide an exteriorly projecting; fuse-like portion'to be ignited when setting off the device, which arrangement is shown in Figures 1 and of thedrawings. If desired, however, instead of arranging the carrier sheet 7, the same may be crumpled up with the corners 7 enclosed within the casing and the body of the sheet carrying the pastilles or lozenges 8 of pyrotechnical composition disclosed at the opening 2 otthe casing and thus exposed to the flame of a match, when the latter is applied" at. the opening 2 to ignite the carrier sheet, which arrangement is shown in Figure 5 of the drawings.

The carrier sheet 7 and its pastilles or lozenges S of pyrotechnical composition being enclosed in the casing in either manner above described, the device ready "for use. In operation, the carrier sheet 7 is ignited and burns, whereby the combustion thereof in turnignites the pastilles or lozenges 8, so that as the latter are thus set off a succession of intermittent explosions or detonations will occur, which will continue for a comparatively long time. Air'to support the combustion of the carrier sheet and the pastilles or lozenges of pyrotechnical composition will find its way into the interior of the casing through the ventilat ing' perforations 5 provided in the sides of the casing. The detonating material being enclosed within the casing 1 cannot .i'ly about when set oil, and the hollow interior of the casing tends to emphasize the reportsor sound of the detonations. It will thus be apparent that the device is unusually safe for child'rens amusement since there is little danger of scattering: particles of live or smoldering fragments burning the child, igniting its clothing. or objects in the vicinity wherein the device is set off. Furthermore, owing to the spaced arrangement or separation of the members of thegroup of pastilles or lozenges of pyrotechnical com position 8 onthe carrier sheet, the'ignit-ion of the same is sure to be intermittentso that a succession of detonations similar to that produced by igniting; a whole pack of oldt'ashioned fire-crackers is produced. The effect of a succession of intermittent detonations is increased when the particular compositionabove referred to is employed for the pastilles or lozenges, since it is characteristic of such composition that it burns slowly and produces intermittent detonations while burning, so that in addition to the separate reports of the different individual pastillcs or lozenges upon ignition thereof each such individual pastille or lozenge will of itself produce a plurality of intermittent reports.

I am aware that some changes may be made in the arrangements and combinations ofthe parts making up the device, as. Well as in the details of the construction and composition of said parts, without departing from the scope of this invention as above set forth, and as defined in thet'ollowing' claims. Hence, I do not limit myselt to the exact arrangements and combinations of the various parts as described in the above specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
